Pressure induced Superconductivity and location of Fermi energy at Dirac point in BiSbTe3
Vinod K. Gangwar, Shiv Kumar, Mahima Singh +8
We have grown single-crystal BiSbTe3 3D TI sample and studied structural, TE as well as pressure dependent magneto-transport properties. Large positive Seebeck coefficient confirme…
Giant longitudinal negative magneto-resistance under perpendicular magnetic field in BiFeSeS Topological insulators
Rahul Singh, Vinod K. Gangwar, Abhishek Singh +5
The magnetic, magneto-transport and ARPES studies of Fe and S co-doped Bi2Se3 were investigated. With doping concentration magneto-resistance (MR) gradually decreases and for a cer…
Probing the multi spin-phonon coupling and local B-site disorder in Pr2CoFeO6 by Raman spectroscopy and correlation with its electronic structure by X-ray photoemission spectroscopy
Arkadeb Pal, Surajit Ghosh, Amish G. Joshi +5
Electronic structure near Fermi level of Pr2CoFeO6 (at 300 K) was investigated by X-ray photoemission spectroscopy (XPS) technique. All three cations, i.e., Pr, Co and Fe were foun…
Local excitons in silicon induced by SiGe quantum huts
Arka Bikash Dey, Milan K Sanyal, Swapnil Patil +4
Conversion of Si to a direct bandgap semiconductor for optoelectronic application is a great challenge for many decades. It is proposed that embedment of suitable sized quantum dot…
Hidden phase in parent Fe-pnictide superconductors
Khadiza Ali, Ganesh Adhikary, Sangeeta Thakur +9
We investigate the origin of exoticity in Fe-based systems via studying the Fermiology of CaFe2As2 employing Angle Resolved Photoemission spectroscopy (ARPES). While the Fermi surf…
Observation of pseudogap in MgB2
S. Patil, V. R. R. Medicherla, Khadiza Ali +5
Pseudogap phase in superconductors continues to be an outstanding puzzle that differentiates unconventional superconductors from the conventional ones (BCS-superconductors). Employ…
